Abstract (en)
[origin: EP3367688A1] A predicted image is generated by means of a method with which it is easy for parallel processing for a plurality of pixels to be executed, in a case where each pixel of the predicted image is derived according to a distance from a reference region and with reference to an unfiltered reference pixel. A predicted pixel value constituting the predicted image is derived by applying weighted sum in which a weighting coefficient is used with respect to a filtered predicted pixel value in a target pixel within a prediction block, and at least one or more unfiltered reference pixel values, and the weighting coefficient for the unfiltered reference pixel values is derived as a product of a reference intensity coefficient that is determined according to a prediction direction indicated by a prediction mode, and a distance weighting that monotonically decreases according to an increase in a reference distance for the target pixel.
